thresholds. As the sin wave input threshold is increased, the
low side clamps become active (Figure 4). Increasing the
amplitude further (Figure 5), the high−side clamp becomes
active. These internal clamps allow for voltages up to −250 V
and 250 V on the sensor side of the setup (with R1 = R2 =
22 k) (reference the diagram page 1).
function has on the circuit. The input threshold (negative) is
switched from a threshold of −160 mV to +160 mV when
DIAG goes from a low to a high. There is no hysteresis when
DIAG is high.
